MTV

One of the stars of MTV's new dating show ... FOR SINGLES ... left out a very important detail on his application -- he's secretly married with a newborn baby.

23-year old Dre McCoy has been acting like a real ladies' man on "Are You the One?" -- but according to a wedding registry ... he tied the knot with a girl named Tiffany Gore less than a year ago.

And up until very recently, all signs pointed to a happy union -- recent photos (above) showed the couple wearing wedding rings and posing together at the hospital during the birth of their child.

Pretty crazy considering he's been dating multiple women on the show -- and MTV sources tell us people at the network were completely unaware of Dre's marital status going into the show.

However, we're told MTV just recently found out Dre and Tiffany are separated and planning to divorce ... which means tonight's episode will be very interesting.

It's all about exes ... and we're told Tiffany will be making an appearance.

Farrah Abraham is as fake as her boobs ... having the nerve to claim she never signed on for a porn sequel. She did, and we have the email to prove it.

Abraham is upset over Vivid releasing a follow-up video to "Backdoor Teen Mom" ... claiming she never approved a sequel.

Small problem ... We have an email Farrah sent to Vivid ... in which she gives the porn company the right "to release video or Videos(s)." Plural times 2.

Farrah says she's a public figure, not a porn star. Fact is she's both -- she's a porn star who has a public figure, from both the front and the rear.

Refusing to age with even a hint of grace, 55-year-old Madonna clung desperately to her youth on stage last night with Miley Cyrus ... like a narcissistic mother trying to be hotter than her daughter.

It's just ... painful.

Madonna and Miley (who's 21 by the way) hit the stage together last night in cowboy get-ups for Miley's "MTV Unplugged" show in Hollywood ... but it felt more like a TLC special.

It's just the latest in Madonna's "I'm still hip" campaign -- in 2012, she named her tour "MDNA" an obvious play on MDMA ... and even once asked a crowd if they'd "seen Molly" ... a sad out-of-the-loop reference to the same drug.

Oh yeah, and a couple weeks ago she referred to her white son as "dis n**ga." Good lord.

Giants punter Steve Weatherford tells TMZ Sports ... he's obsessed with "Teen Mom" ... but despite his super-fandom, the NFL star says he draws the line at Farrah Abraham's sex tape.

Weatherford admits he's stumbled upon a free preview of Farrah's venture into porn, but says he can't justify shelling out money to watch the entire cinematic experience.

"I'm not paying $5 to watch Farrah."

A former MTV reality star says she's the victim of a botched boob job ... and it left her left nipple so messed up, it "oozed" for several years ... this according to a lawsuit obtained by TMZ.

The woman behind the suit is Tiffany Rowe-Storms, who starred on "There and Back" in 2006 with then fiance Ashley Parker Angel from O-Town (they've since broken up).

In her suit, Tiffany claims she went under the knife for a routine breast augmentation surgery back in 2008 ... but something went horribly wrong, and "open sores developed" around her left nipple.

Tiffany claims the problems got worse ... and she was hospitalized for pain in her left nipple in 2010 -- where emergency room personnel discovered signs of staph infection.

In her suit, Tif claims she went to another surgeon in 2012 who found "chronic oozing and infection in her left breast."

Tif says the other surgeon also discovered a strain of staph in her left breast that was so severe, she was "at risk of losing her arm or worse, had it spread."

Snooki and JWoww are handing NJ Gov. Chris Christie a big fat gift -- telling TMZ they're giving their archenemy a pass on the whole Bridgegate fiasco.

Of course, the "Jersey Shore" alums have a nasty past with the guv -- he's accused them of giving Jersey a black eye ... and they've called him "retarded" (see below).

So, before Christie delivered his State of the State address -- we asked if their old buddy should be impeached over the scandal.

Their reaction was NOT at all what we expected considering their history.

Two down, Christie ... several million other NY/NJ commuters to go.

But while the old man dong was out in full force ... an uncomfortable looking Olivia eventually laughed the whole thing off.

Former "Teen Mom" star Maci Bookout had a momcation in Miami this week ... and with no kid to look after, the 22-year-old let everyone know it was BOOZIN' TIME!!!

Sportin' a shirt that read, "Off Duty," Bookout was seen smokin' ciggies, drinking beer and even swiggin' a champagne cocktail on the beach.

Bookout also posted video of a dancing session in her hotel ... good times.

Of course, Bookout has a 5-year-old son Bentley, but he was reportedly at home with his father Ryan Edwards.

Former "Jersey Shore" star Angelina Pivarnick hasn't appeared on MTV for years ... and after failing to catch fire in the entertainment world -- the Staten Island Dump is giving up and getting a job.

Pivarnick was just accepted into an EMT school in NYC where she will train for the next 3 months ... and then, assuming she actually shows up, Angelina will be certified.

Angelina tells us, "Being the 'Jersey Shore' bitch is in the past ... now, my future is saving lives."

David Rainey -- AKA Puck from "The Real World" -- is going back to school -- domestic violence school ... and if he graduates with honors, he won't go to jail.

Rainey copped a plea in his criminal case -- he was accused of hurting his live-in girlfriend and faced one year in jail.

Rainey got into an argument with his girlfriend in July and allegedly scratched and bruised her ... then slammed the phone down when she tried to call 911.

Rainey pled guilty to domestic violence and dissuading a witness -- both misdemeanors. He was sentenced to 3 years probation and ordered to attend a 1-year domestic violence program.

The judge gave Rainey credit for the 15 days he spent in the slammer.

Rainey had a similar run in back in 2011, when he was arrested for felony domestic violence. And he served prison time in 2012 for stalking a woman.

Maybe these women should learn a lesson from the 1994 "Real World" housemates ... and kick his ass out.

Weston Gosa -- the dude who knocked up Whitney Purvis on "16 & Pregnant" -- was arrested again Tuesday ... and his mug shot is the absolute best of the trilogy.

Law enforcement sources tell us ... Weston was pulled over in Georgia for speeding and driving on a suspended license. He's currently being held at the Floyd County Jail in Rome, GA on a $1,710 bond.

As we previously reported -- Weston was busted last December for smashing some electronics ... and popped again last July after allegedly crashing his car while driving under the influence (which spawned the infamous "sleeping mug shot").

Are the people who cast that show that good ... or just lucky?

Jwoww isn't just gonna squeeze out a kid in July, she's also gonna push out a big ol' steaming dump ... so says her "Jersey Shore" BFF Snooki.

Jwoww made the baby announcement on Christmas Day ... and hours later, Snooki (who already has a kid) posted a screen grab of a recent text convo they had, in which Snooks eloquently describes the miracle of child birth.

As for JWoww -- real name Jenny Farley -- she posted a picture of her growing fetus on Instagram ... along with a note from herself and fiance/baby daddy Roger.

"Teen Mom" star Jenelle Evans' potty mouth got her locked up in South Carolina yesterday ... after cops tried muzzling her during an argument with her boyfriend and she refused.

Police were dispatched 2 separate times to Evans' home yesterday -- both times for loudly arguing with her boyfriend outside ... according to reports.

Cops say Jenelle's BF told them the MTV star locked him out of the house during an argument ... but he agreed to go for a walk and cool off -- so officers left.

Shortly after, they were dispatched again ... and reportedly found her boyfriend had climbed in the house through a window -- which caused Jenelle to lock herself inside the bathroom.

Police handled the situation before attempting to leave -- but Janelle started yelling cuss words outside the house ... and when she refused to stop they took her into custody for "breach of the peace."

Worst part ... Janelle is still on probation -- meaning she could be facing additional jail time if convicted.

Janelle was only in jail for about an hour.

Parenthood has clearly not cramped Pauly D's style .... he happily strolled out of Bootsy Bellows nightclub in West Hollywood late last night ... but there's no doubt -- being a father is front and center in his brain.

Check out the video ... it's not so much what Pauly says -- we know he's fighting for full custody and it's nasty -- but you can see and hear how much he loves his kid.

It's pretty rare when celebs come off so real and unfiltered.

Day 26 -- the boy band masterminded by Sean "Diddy" Combs on MTV's "Making the Band 4" -- IS TOTALLY REUNITING FOR A NEW TOUR ... TMZ has learned.

A rep for Day 26 tells us ... the band, which was handpicked by Diddy on the 2007 show, is planning a 30-city tour starting in the Spring of 2014 ... and it's gonna include ALL of the original members.

Back in the day, D26 produced 2 albums before trouble began. Qwanell "Que" Mosley was kicked out of the group in 2009 because of disagreements with management.

The whole band broke up in the summer of 2012 ... and there've been rumors of a reunion ever since. It wasn't until Que climbed on board that it became a reality.

As for Diddy ... we're told he's NOT part of the resurrected band ... but he's already given the boys his blessing.

Pauly D better learn to duck and cover ... 'cause his baby mama had no qualms about beating the crap out of another guy who knocked her up ... according to police records obtained by TMZ.

We've learned ... Amanda Markert was arrested in July 2009 for opening a can of whoopass on her first baby daddy -- Lance Gerbino -- leaving him with bloody lips, a nasty gash above his eye and injuries inside his mouth.

Gerbino tells TMZ ... Amanda had been out drinking with friends ... and was pissed because she had to come home to help take care of their infant son.

He claims Markert just started "going crazy" ... wailing on his face with her fists while she was holding their son. Gerbino felt the baby was in danger ... and that's why he called police.

According to police records, Markert turned herself in to cops --booked under her legal name, Amareda Markert -- but the assault charge was eventually dismissed after she completed an anger management course.

As we've reported, Markert and Pauly D are involved in an ugly custody fight over their 6-month old daughter, Amabella ... and they've both been very clear about how much they hate each other.

We contacted Amanda for comment on the domestic violence case ... she hung up on us.
